Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed April 6, 1908. Serial No. 425,386.

To all whom it may concern:

Be it known that I, EPPA H..RYON, a citizen of the United States, residing at Worces- Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to looms, and to that class of looms shown and described in my pending application for Letters Patent, serial N 0. 358,847, and my invention particularly relates to a modified construction of some parts of the mechanisms shown and described in said application.

In my present improvements I provide diiferent operating mechanism for the oscillating or vibrating lever, designated by the reference numeral 69 in said application, which lever causes the starting tooth to be moved into the path of an operating pinion, to operate mechanism to cause the shuttle to be changed. I make use of an indicator chain, and through pattern surfaces thereon, and pattern indicating levers, and connections therefrom to a lever, and from said lever to said oscillating lever 69, communicate a positive movement to said lever 69 at the proper time. I have also changed the construction of the positioning lever, designated by the numeral 92 in said application, for the oscillating lever 69 above referred to, and I have also changed the construction of the compound levers which, through connections to the positioning lever,causes an up and down movement of said positioning lever for said oscillating lever, according the shuttle to be changed, all as will be hereinafter fully described.

I have only shown in the drawings my improvements, and parts of the mechanisms connected therewith shown and described in my said application, sufificient to enable those skilled in the art to understand the construction and operation of my improvements.

Referring to the drawings :-Figure 1 is a front view of the left hand end of a loom of the class above referred to, showing parts of the Knowles head motion, and my im provements combined therewith, and three drop shuttle boxes, and my switch shuttle box combined therewith. Fig. 2 shows, on

an enlarged scale, an end View of some of the parts shown in Fig. 1, looking in the direction of arrow (4, same figure. A number of the parts shown in Fig. 1, are not shown in. this figure. Fig. 3 is a plan view of the parts shown in Fig. 2, looking in the direc- -tion of arrow 6, same figure. Fig. 4 is a sec 'tion, on line 4, 4, Fig. 3, looking in the direction of arrow 0, same figure. Fig. 5 is an end vlew of the parts shown 1n Flg. 2,

looking in the direction of arrow 03, same to describe herein in detail, the modified construction of my improvements shown and described in said application.

In the accompanying drawings, 1 is the loom side or end, 2 the arch stand, 3 the arch, 4 the head frame, having thereon the head motion of the well known Knowles type, shown and described in U. S. Reissue Letters Patent, No. 7,784, comprising the upper cylinder gear 5, the lower cylinder gear 6, the intermediate vibrator gear 7 carried on the vibrator lever 8, which is pivotally mounted at its outer end on the transverse rod 9. The vibrator gear 7 is connected, through a vibrator connector, not shown, to the lever of the box motion, not shown, which has a chain 13 attached thereto, which chain passes over guide sheaves 19, 20, and 21, and is attached to the vertically moving shuttle box rod 22, carrying in this instance the three ordinary drop or change shuttle boxes 23, and the switch shuttle box 24, see Fig. 1.

The head motion above described is operated through an upright driven shaft, not shown. A pinion 30 on the lower cylinder shaft 6', meshes with and drives a gear 31 fast on the pattern chain cylinder shaft 32, carrying the shuttle box pattern chain cylinder, and the shuttle box pattern chain, to be hereinafter described.

35 is the breastbeam, 36 the lay sword, pivotally mounted at its lower end, 37 the lay beam, and 38 the hand rail.

It will be understood that on the opposite end of the loom, not shown, there are in this instance four drop or change shuttle boxes of ordinary construction, which are connected with the shuttle box operating mechanism of the head motion, in the usual way.

The u ori ht stand 54 see Fi 1 is secured to the head frame, or some stationary part of the loom, and has a series of notches 54, in this instance six notches, in one edge thereof, in this instance the outer edge, corresponding to the number of shuttles to be used in the loom, said shuttles preferably carrying filling of a different color or character. 'There are also a series of rests or lips 54 on the plate 54, see Fig. 4. In connection with the upright notched stand 54 is used an indicator lever 55, see Fig. 2, having the hub 55 thereon extending between the forked shaped end 56 on an arm 56, and pivotally mounted on said arm by a bolt 57, see Fig. 2. The lever 55 has an engaging end 55 at the front of the loom, to be manually operated by the weaver, and to be removed from any one of the rests or notches 54 of the stand 54, and placed in any one of the other notches 54', according to the desired change of a shuttle, numbered correspondingly to a numbered notch 54 on the upright stand 54.

The arm 56, see Fig. 3, has a hub 56 thereon, which is pivotally mounted on a bushing, which bushing, not shown, is mounted on the end of a stud 60, which is supported in the stationary part of the head frame, and has a washer 61 and a nut 61, on its end, see Figs. 3 and 4. The lever 55 has attached thereto one end of a helically coiled tension spring 62; the other end of said spring is attached to the arm 56. The spring 62 acts to yieldingly hold the engaging end 55" of the lever 55 in the notch 54 of the stand 54, in which it is placed.

On the lever 55, on two studs 63 and 63', are pivotally mounted two latches 64 and 65, see Fig. 3; each of the latches 64 and 65 has an extension 64 and 65 thereon, each of which extensions is adapted to engage a proj ection 66 and 67, respectively, on the lever 55, to limit the pivotal movement in one direction of said latches.

A helically coiled tension spring 68 is attached at one end to one latch 64, and at its other end to the other latch 65, and is adapted to draw the latches toward each other, and hold the extensions 64 and 65 against the stops 66 and 67, see Fig. 3.

The object of the latches 64 and 65 is to stop the movement of the oscillating or vibrating lever 69, when the offset end 69 on said lever comes between said latches 64 and 65, and causes the starting of the shuttle changing mechanism.

The box pattern chain cylinder shaft 32,

see Fig. 5, has a pattern chain cylinder 70 thereon carrying a pattern chain 71, made up of links and bars, carrying rolls 71 and tubes 71". The pattern chain 71 operates the compound lever mechanism.

All of the above mentioned parts may be of the same construction, and correspond to similar parts shown and described in my said pending application.

I will now describe the compound lever mechanism shown in the drawings, which embodies some of my improvements, and is different from the compound lever mechanism shown and described in my said application for a patent, Serial No. 358,487.

Referring particularly to Figs. 3 and 5, in which said compound lever mechanism is shown, I provide three intermediate pattern levers or indicators 72 73 and 74, which extend over the pattern chain 71, and are raised and lowered by the rolls and tubes on said chain, as the same is rotated. The hubs 72 73, and 74 of the levers 79., 7 3, and 74 are loosely mounted, in this instance on a stud 75 carried on a hanger 7 5. In connection with the three intermediate pattern indicator levers 7 2, 73, and 74 is used a com pound lever, consisting of a lever 74 having its hub 7 4 pivotally mounted on a stub 7 5". The inner end of the lever 74 extends over the intermediate pat-tern indicator lever 74, and said lever 74 has an extension 74"" thereon, carrying a stud 76 on which is mounted the hub 7 7 of a second lever 77. The inner end of the lever 77 a is curved upwardly, as shown by broken lines in Fig. 5, and extends over the hub 74 of the lever 74, and over and in a position to'be engaged by the intermediate pattern indicator lever 73*. The lever 77 has a rearwardly extending extension 77 thereon, carrying a stud 7 8 on which is mounted the hub 79 of a lever 79*. The lever 79 is curved upwardly, and its inner end extends over the intermediate pattern indicator lever 72 and is adapted to be engaged by said lever. An outward extension 79 on the lever 7 9, is connected by a link 83, with an arm 84 fast on a rock shaft 85. On the opposite end of the rock shaft 85 is fast an arm 86, see Fig. 4, which has an elongated opening 86 therein, which is adjustably attached by a bolt 87 and nut 88 to the lower end of the connector 89. The up per end of the connector 89 is attached to the positioning lever 92 for the oscillating lever 69. On the rock shaft 85 is a helically coiled torsion spring 85, which acts to return the rock shaft 85 to its normal position.

The vertical movement of the arm 92, according to the indications of the pattern chain 71 and the movement of the compound lever mechanism above described, causes a similar vertical movement of the oscillating lever 69, to brin it between the latches 64 and 65 on the indicating lever 55, according.

to the position of said indicating lever relative to the notches 54 on the upright stand 54, all as fully described in my said application for Letters Patent, Serial No. 358,847.

The vibrating or oscillating lever 69 is adapted to have an oscillating motion in a horizontal plane, and also a rocking motion in a vertical plane, and in this instance has at its inner end a ring shaped formation 69", which is pivotally connected by screws 93 with a ring 94, see Fig. 4, extending loosely in an annular groove in a cam 95, which is loosely mountedon the extended hub 96 of a mutilated gear 96. The hub 96 of the mutilated gear 96 is loosely mounted on a stationary pin 60. The mutilated gear 96 has also fast on its extended hub 96, see Fig. 3, a cam 97. All of these parts are of the same construction and operation as similar parts in my said application.

The positioning lever 92 has in this instance a hub 92, which is loosely mounted on the stationary stud 60, and on said lever 92 are in this instance two upright studs 92 each carrying a helically coiled torsion spring 92 one end of which is fast to a stud, and the other end 92, see Fig. 4, extends beyond the end of the lever 92, and in the path of and adapted to engage the oscillating lever 69, to return said lever to its normal central position. The oscillating lever 69 has an oscillating movement communicated thereto, in this instance through a rod 99, connected at one end with an extension 69 on the oscillating lever 69, and

connected at its other end with an extension 100 on a lever 100. The lever 100 has a hub pivotally mounted on a stud 101 on a stand 102, see Figs. 2 and 5. One arm of the lever 100 is connected by a rod or connector 103 with the end of a lever 104, having a hub 104 pivotally mounted on the stud said lever 104 extends over a pat tern surface on the pattern chain 71, and is raised or lowered as said chain is rotated, according to the pattern indications. The other arm of the lever 100 is connected, through a rod or connector 105, with a second pattern lever 106, having its hub 106 loosely mounted on the stud 75. The pattern lever 106 extends over the pattern chain 71, and is acted on by a pattern indicating sur face on said chain, to be raised or lowered as said chain is rotated, according to the pattern indications.

Through the rotation of the pattern chain 71, and the movement of the levers 104, and 106, according to the pattern indicatingsurfaces on said chain, a positive rocking mothrough the rod 99, an oscillating movement is communicated to the oscillating lever 69, to cause said lever to be moved in one direction or the other; said lever is also raised or lowered with the positioning lever 92, all as fully described in my said application.

When the oscillating lever 69, in the up and down movement of the positioning lever 92, extends between the latches 64 and 65 on the lever 55, so that the oscillating movement of said lever 69 is prevented, the movement of'the pattern indicator levers 104, and 106, through connectors 103 and 105, lever 100, and connector 99, will move the collar 95 on the extended hub 96 of the mutilated gear 96, toward the mutilated gear 96. The collar 95 has an extension or arm 95 thereon, see Fig. 4, which is connected with a lever 109, which is of ring shape at its central portion, and oscillates on screws 110 and 110. The extended ends 109 of the lever 109, form starting teeth to be moved into the path of a projection 111 on the mutilated pinion 111, so that the revolution of said pinion 111 will cause the revolution of the mutilated gear 96. The mutilated pinion 111 is loosely mounted on a stud 112, see Fig. 1, secured to the frame, and has attached thereto a second pinion 113, see Fig. 3, which meshes with and is driven by a pinion 114 fast on the upper cylinder gear shaft 5 of the head motion.

The rotation of the mutilated pinion 96, when one end 109 of the oscillating lever 109 is moved in the path of the mutilated pinion 111 on the stopping of the oscillating lever 69, will cause the rotation of the cam 97, The rotation of the cam 97, through intermediate connections, not shown, to sliding runs on the vibrator levers, not shown, which extend over the box pattern chain, not shown, will cause, through connections to the shuttle boxes 23, the switch shuttle box 24 to be moved to the line of the race-way of the lay, to receive in the outer cell the shuttle to be exchanged, and at the proper time to have the new shuttle picked from the inner cell of the swivel shuttle box 24, all as fully described in my said application, Serial No. 358,847. 7

From the above description in connection with the drawings the operation of my improvements will be readily understood by those skilled in the art.

It will be understood that the results obtained from the use of my present improvements herein described, correspond to the results obtained from my improvements shown and described in my pending application for Letters Patent of the United States, Serial No. 358,847, above referred to, as my present improvements relate only, as above tion is communicated to the lever 100, and I stated, to a modified construction of some varied if desired.

I have used the Word manually, and I intend to cover by this Word, a foot-operated device or any non-automatic operated lever, or device.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a loom of the class described, the combination with shifting shuttle boxes, mechanism connected With said shuttle boxes to cause the operation of the same to effect. a change of shuttles, and an indicator lever to be moved by the operator, of a pattern chain having pattern surfaces thereon, and connections from said pattern surfaces to said indicator lever, to bring into operation said mechanism connected With the shuttle boxes.
